Autotracer vs VTracer

Autotracer has no write-up on Specifiction yet; its figures are above.

VTracer turns raster images such as JPG and PNG into compact SVG vector graphics. It handles graphics and photographs, with support for high-resolution scans as well as low-resolution pixel art. Its color-processing pipeline can retain colors or constrain output to a fixed palette or maximum color count. Users can choose a web app, desktop app, or command-line tool; developers can also use a Rust library, Python native extension, or Node.js WebAssembly package. The web app accepts images by drag-and-drop, paste, or file selection, with clustering and curve-fitting controls. Desktop features include an A/B comparator, curve inspector, curve simplification, seam-free cutout, watershed clustering, adaptive black-and-white thresholding, and fixed palettes. The command-line tool supports presets, clustering options, curve-fitting modes, and output optimization. The Node.js package decodes PNG, JPEG, GIF, BMP, and WebP; other formats can be separately decoded and supplied as raw RGBA pixels. VTracer is free and open source under the MIT license, with desktop downloads for Windows, macOS, and Linux.
